Uplink Scheduling in a Mobile Telecommunication Network

1. A node B base station comprising: a downlink data scheduler; an uplink data scheduler; means for transferring information associated with a downlink data transfer of a data packet received from a data packet network intended for a user equipment (UE) from said downlink data scheduler to said uplink data scheduler, wherein the uplink data scheduler is configured to schedule an initial uplink transfer of uplink data to be transmitted by the user equipment (UE) for a first time over a radio interface using said information as a result of transmitting said downlink data over the radio interface, wherein the uplink data scheduler is further configured to schedule the initial uplink transfer of the uplink data by the user equipment (UE) for the first time over the radio interface independently and regardless of whether a request to transmit the data by the user equipment (UE) has been received by the node B base station.

2. The node B base station according to claim 1 , wherein the uplink transfer of the data is in response to the downlink data transfer.

3. The node B base station according to claim 1 , further comprising means for transmitting a scheduling grant indicator indicating when and/or how the UE is allowed to transmit the uplink data over the radio interface to the node B.

4. The node B base station according to claim 1 , further comprising means for transmitting a scheduling grant indicator simultaneously with the transmission of said downlink data.

5. The node B base station according to claim 1 , further comprising means for transmitting a scheduling grant indicator included in a downlink message transmitted on a same channel as the downlink data transmission.

6. The node B base station according to claim 1 , further comprising means for transmitting a scheduling grant indicator on a downlink channel adapted to schedule the initial uplink transfer of the uplink data.

7. The node B base station according to claim 6 , wherein the downlink channel adapted to schedule the uplink data transfer is an enhanced Absolute Grant Channel.

8. The node B base station according to claim 1 , wherein the uplink data scheduler is further configured to schedule the initial uplink transfer of the uplink data within a predefined time period after the downlink data is received.

9. The node B base station according to claim 1 , further comprising means for allocating an amount of uplink resources in relation to an amount of transmitted downlink data.

10. The node B base station according to claim 1 , wherein the node B is implemented in a Universal Mobile Telephone System.

11. A method in a Node B base station comprising a downlink data scheduler and an uplink data scheduler the method comprising the steps of: transferring information associated with a downlink data transfer of a data packet received from a data packet network intended for a user equipment (UE) from said downlink data scheduler to said uplink data scheduler, and scheduling an initial uplink transfer of uplink data to be transmitted by the user equipment (UE) for a first time over a radio interface using said information as a result of transmitting said downlink data over the radio interface including scheduling the initial uplink transfer of the uplink data by the user equipment (UE) for the first time over the radio interface independently and regardless of whether a request to transmit the data by the user equipment (UE) has been received by the node B base station.

12. The method according to claim 11 , wherein the uplink transfer is in response to the downlink data transfer.

13. The method according to claim 11 , wherein the step of scheduling the uplink transfer comprises the further step of transmitting a scheduling grant indicator indicating when and/or how the UE is allowed to initially transmit the uplink data over the radio interface to the node B base station.

14. The method according to claim 13 , wherein the step of scheduling the uplink transfer comprises the step of transmitting a scheduling grant indicator simultaneously as the transmission of said downlink data.

15. The method according to claim 14 , wherein the step of scheduling the uplink transfer comprises the step of transmitting a scheduling grant indicator included in a downlink message transmitted on a same channel as the downlink data transmission.

16. The method according to claim 11 , wherein the step of scheduling the uplink transfer comprises the step of transmitting a scheduling grant indicator on a downlink channel adapted to schedule the initial uplink transfer of the uplink data.

17. The method according to claim 16 , wherein the downlink channel adapted to schedule the initial uplink transfer of the uplink data is an enhanced Absolute Grant Channel.

18. The method according to claim 11 , wherein the step of scheduling the initial uplink transfer of the uplink data comprises the step of scheduling the initial uplink transfer of the uplink data within a predefined time period after the downlink data is received.

19. The method according to claim 11 , wherein the step of scheduling the initial uplink transfer of the uplink data comprises the step of allocating an amount of uplink resources in relation to an amount of transmitted downlink data.
